QR code best practices
- 1
Contrast ratio above 4.5:1
Dark modules on a light background. Avoid inverted (light-on-dark) codes — they fail on a majority of older Android cameras. Test contrast with a WCAG checker.
- 2
Quiet zone of 4+ modules
Leave a margin of at least four blank modules on every side of the code. The scanner needs that whitespace to detect the matrix boundary.
- 3
Match error correction to the use case
L for clean indoor prints. M default. Q for codes with a centred logo. H for outdoor signage and big logo overlays. Don't over-correct — denser codes need larger print sizes.
- 4
Use dynamic redirects on printed material
Any QR that lives more than a week in print should be dynamic. The cost of reprinting a static code that points to a dead URL is always higher than upgrading to dynamic.
- 5
Mobile-optimised landing page
The destination page must load in under 2 seconds on a 4G phone. Avoid full-screen modals, autoplaying video, and cookie banners that fire before content appears.
Frequently asked questions
What is QRCode Suite?
QRCode Suite is a standalone QR code platform: create a free account and generate branded, dynamic QR codes in the browser — no WordPress required. Connectors bring the same codes to WordPress and WooCommerce, where orders can be attributed to specific QR codes.
Does QRCode Suite work without WordPress?
Yes. QRCode Suite is a standalone SaaS — sign up, create QR codes, and track scans entirely on qrcode-suite.com. The WordPress plugin is an optional connector that brings your codes into wp-admin and adds WooCommerce order attribution.
Does QRCode Suite require a separate subscription?
The Free plan is available at no cost — no credit card required. Paid plans (Pro €9, Business €29, Agency €79 per month) unlock unlimited codes, redirect rules, and more. There is no separate per-scan fee.
What QR code types does QRCode Suite support?
QRCode Suite supports 22 QR code types: Static URL, Dynamic URL, Plain Text, Phone, Email, Location, Link Hub, SMS, WhatsApp, Wi-Fi, vCard, Social profile, PDF, File download, App download, Coupon, Calendar event, Lead capture form, Review collection, Wholesale inquiry, Loyalty reward, and Custom payload.
Can I change the destination of a QR code after printing it?
Yes. Dynamic QR codes use a short redirect URL. You can update the destination from your dashboard at any time without generating or reprinting the code.
Is QRCode Suite GDPR-compliant?
QRCode Suite is built with GDPR in mind: raw IP addresses are never stored — visitors are counted with keyed hashes — bot traffic is filtered automatically, and scan events are purged once your plan retention window elapses. Consult your legal team for your specific obligations.
